Can be used for Heltec ESP32 LoRa products only
Essential parts of the source code are obfuscated (compiled to assembly).
“An unique license relate to Chip ID is needed, you can check your license here: Search ChipID relative License – Heltec Automation”

(therefore less attractive for developers).
